The error correction term \(\lambda _{EC}\)  is equal to the classical information exchanged during the reconciliation stage, this is included in the estimate of the amount of privacy amplification needed. In practice, we can keep track of the bits exchanged and thus \(\lambda _{EC}\)  is known and not subject to statistical uncertainty. However, to model the systems performance we need an estimate of \(\lambda _{EC}\)  and we use the sophisticated estimate introduce in [1]}, as discussed in [2]}.
